What is the impact of a terminal disclaimer on an abandoned application?

A terminal disclaimer can have significant implications for an abandoned application. The MPEP 711.02(b) provides guidance on this matter:

The mere existence of a recorded terminal disclaimer filed to obviate a double patenting rejection does not preclude an application from becoming abandoned for failure to reply to an Office action. The establishment of the terminal disclaimer creates only a formal relationship between applications or patents; it does not revive an abandoned application.

Key points to understand:

  • A terminal disclaimer alone does not prevent abandonment
  • It does not automatically revive an abandoned application
  • Applicants must still respond to Office actions to avoid abandonment
  • If an application becomes abandoned, a proper petition for revival is necessary, regardless of any terminal disclaimer
